Abstract

The sheet GO was mixed with the phase change material microcapsule and prepared into a photothermal suspension, and its optical properties and photothermal conversion properties were explored and analyzed mechanism of GO effects on the photothermal properties of phase transition materials. The results show that the optical performance and photothermal conversion performance of the compound suspension are significantly improved compared with the microcapsule suspension without GO. The addition of 0.03% graphene oxide to the microcapsule suspension of 0.1% phase change material increased the extinction coefficient at a specific wavelength by 522.30%. The temperature rise and photothermal efficiency of the indoor photothermal experiments were the highest when 0.1% GO was added, which were 63.7 ℃ and 57.49%, the temperature was increased by 59.2 ℃ in outdoor photothermal experiments.
